Answers
Step-by-step explanation:
a fish tank can hold 36 liters of water when filled to the brim. is 3/8 filled. if 1/3 of the water is removed, how much more water must be added in order to the tank to the brim?
The amount of water that needs to be added in the fish tank in order to fill the tank to the brim = 29.25 liters.
Given:
Volume of fish tank = 36 liters
To find:
How much water to be added in order to fill the tank to the brim.
Step by step explanation:
Step 1:
According to the question, the given tank is 3/8th filled with water.
∴ The amount of water the fish tank is holding = 36 * 3/8
= 108/8
= 13.5 liters
⇒ The amount of water in the fish tank = 13.5 liters
Step 2:
Now, half of the water filled in the tank is removed.
∴ The amount of water remaining in the fish tank = 13.5/2
= 6.75 liters
⇒ The amount of water remaining in the fish tank = 6.75 liters
Step 3:
The amount of water that must be added in order to fill the tank up to the brim = Total amount of water the tank can hold - The amount of water
present in the tank at the present moment.
= 36 - 6.75
= 29.25 liters.
The amount of water that needs to be added in the fish tank in order to fill the tank to the brim = 29.25 liters.
